Inline stainless steel skin pass mill technology In recent years, because of the advantages of simplifying processing with offline skin pass mills and high-tension skin pass mill rolling, it has been a common practice to install skin pass mills on the exit side of stainless steel APL/BAL.
SKIN-PASS MILL Excellent Flatness and a Perfect Finish The advantages of skin-pass mills (also known as temper mills) from Primetals Technologies include full compliance with tight strip elongation tolerances; excellent flatness performance; high surface quality with respect to roughness, peak count and low residuals; and the availability of wet and dry skin-passing modes.
1.5% (exceptionally up to 3%). The process step of skin pass rolling is at the very end within the steel processing chain and finally provides the mechanical, surface and geometrical properties required for various applications. If a defined strip surface structure is required, the Skin Pass Mill is working with a textured work roll.
20Hi ZR Mill, HZ Mill. The ZR mill uses ultra-small diameter work rolls to efficiently roll high-hardness materials such as stainless steel, electrical steel strip, and phosphor bronze. To the original high rolling reduction capacity of the mill, we have added the double AS-U (shape control mechanism) originally developed by our company.
In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough.Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is
Skin pass is another type of rolling process. Skin pass rolling is defined as a process in which fine structure give to the newly generated grain. After annealing process so that it become useful for forming operation. In case of skin rolling also known as a skin pass having less reduction around 0.5-1 %.

Tags Pickle Lines, Rolling Mills; Temper Pass or Skin Pass Rolling. Material can be reduced accurately while skin passing. Hot rolled steel coming from a steel mill or pickle line may need to be reduced 1% to 2% in thickness. This can be done on a coil-to-coil temper pass mill or in line on a cut-to length line.
20 High Cluster Mills utilize small diameter work rolls which allow higher reductions on harder materials than other mill configurations. The multi-roll system having employs a unique roll configuration with adjustment capabilities to control strip shape and compensate for the effects of rolling a wide range of different strip widths to very thin thicknesses.

Jul 08, 2013· Fig 1 Texture of galvanized iron sheet. Process of galvanizing. The process of galvanizing steel sheet was developed simultaneously in France and England in 1837. Both of these methods employed a ‘hot dipping’ process to coat steel sheet with zinc. Galvanizing is carried out on cold rolled sheets/cold rolled strips.
the sheet thickness of the incoming sheet was varied depending on the particular skin pass level and the final roll gap was kept at 5 mm. (For Condition 3, an intermediate skin pass with a larger roll gap was included). After skin passing, the distribution of the longitudinal residual stress, σx was determined over the sheet thickness, as shown in
